Abstract
The present invention relates to a fibreoptic switch for enabling one or more of n number of incoming optofibers to be connected selectively with a respective one of m number of outgoing optofibers. According to the invention, the switch includes a matrix block (1) having light transmitting devices (2) which extend in n number of rows and m number of columns between an input side and an output side. On the input side, the incoming optofibers (3) can be displaced linearly along a respective row of the rows of light transmitting devices (2), and the outgoing optofibers (6) on the output side can be displaced linearly along a respective column of the columns of light transmitting devices (2). A selected incoming optofibre (3) can therewith be displaced along its corresponding row to a desired column of light transmitting devices (2), and an outgoing optofiber (6) in a corresponding column can be displaced to a corresponding row of light transmitting devices (2), so as to mutually connect the selected optofibers.
